Abstract
- International audience; We report on the coherent beam combining of seven fiber chirped-pulse amplifiers using a highly scalable architecture. A combining efficiency of 48% is obtained in linear regime, yielding 71 W pump-limited average power after compression, with a phase noise between two fibers as low as λ/38 RMS. The experiment is operated at high B-integral, with only little impact on the combining efficiency as well as on the temporal and spatial properties of the combined beam.
